Texas Instruments PCM1802
The PCM1802 is a high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1802 uses a delta-sigma modulator with 64-times or 128‑times oversampling, and includes a digital decimation filter and high-pass filter (HPF), which removes the DC component of the input signal. For various applications, the PCM1802 supports master and slave modes and four data formats in serial interface.| Part No. | PCM1802 |
